WineBottler development version 1.7.11 comes with some quick fixes for cases, where your new app would just not open if the filename contains spaces. Then it brings all the goodies of Wine 1.7.11, of corse.
Running Inkscape 0.48.4 for Windows with WineBottler on OS X. If you need the latest version, Fullscreen or don't like to install X11.
Thank you Tobias, for helping me fix the startup issue :).
